Beeswax is not the answer for a too-tight fit. It works great
for a fit that loosens up (I use it regularly), but beeswax soaks
into the wood of the mortise when warmed up by the smoke, and the
fit becomes even tighter. If the fit is too tight to start with,
that can make it more difficult or even almost impossible to
disassemble the pipe.
Graphite is the best lubricant for a too-tight fit. Scribbling
with a pencil is for most people the easiest way to do it, but
any form of graphite will work.
If graphite will not cure the problem, beeswax d*mn sure won't,
because it will make the fit tighter (albeit better lubricated)
and the alternative remedy is to take a little bit of material
off the tenon. Repeat, "a little bit of material" off the tenon.
If you have a strip of sandpaper maybe an inch wide, of 300-grit
wet-or-dry or higher, you can make a sort of loop of the
sandpaper at one end and hold that just above the loop with thumb
and forefinger. Then lay the tenon in the loop so it contacts
the sandpaper evenly, and turn it with very light pressure. That
will take off a little material.
Try for fit. If improved, but not enough, try graphite again and
see if that will do the job. If not, lather, rinse, repeat, each
time taking a very little amount of material off the tenon.
There is another way to loosen up the fit, but it is a
consequence of cleaning the pipe regularly with grain alcohol and
will happen automatically if you do that. Most who do not use
grain alcohol are not going to adopt it just to loosen up a tight
fit on a particular pipe.
Basically, grain alcohol is a strong dehydrating agent. Each
molecule of ethanol binds to six molecules of water, and that
loose bundle will evaporate more readily than water molecules
alone. The wood of the mortise dries out, shrinks, and the
mortise-tenon fit loosens. No special effort required.
The problem of course is that the mortise-tenon fit routinely
loosens, even if not too tight. I clean my pipes with grain
alcohol after every smoke, and I am well acquainted with this
effect of grain alcohol. My solution is regular use of beeswax,
to tighten the fit back up. Works for me.
If the issue is mortise-tenon fit that is too tight, if you clean
the pipe with grain alcohol that problem will self-correct. And
if you do not, the remedy is either graphite or remove a little
material.
